True - correct answer True or false. A program mostly
consists of a series of statements, each statement usually
appears on its own line.
False - correct answer True or False. Text in string literals
may not have letters, numbers, spaces, or symbols like "@" or
"#".
True' - correct answer True or False. A string literal can be
surrounded by matching single or double quotes: 'Python rocks!'
or "Python rocks!". Good practice is to use single quotes for
shorter strings, and double quotes for more complicated text or
text that contains single quotes (such as print("Don't eat that!")).
False - correct answer True or False. Python comes pre-
installed on Windows machines.
True - correct answer True or False. Python code can be
written in asimple text editor, such as Notepad (Windows).
True - correct answer True or False. Early high-level
languages included FORTRAN (for "Formula Translation") or
ALGOL (for "Algorithmic Language") languages, which were
,more closely related to how humans thought than were machine
or assembly instructions.
True - correct answer True or False. An assembler translates
an assembly program into machine instructions.
True - correct answer True or False. A high-level language
eases a progrmamers task of writing complex programs.
False - correct answer True or False. Python is not an open-
source language.
False. Python excels at providing powerful programming
paradigms such as object-oriented programming and dynamic
typing. Python incurs additional overhead costs because the
language is interpreted. - correct answer True or False.
Python is a high-level language that excels at creating
exceptionally fast-executing programs.
False. Python was originally designed with readability in mind.
Some of the maxims of Python include "Simple is better than
complex", and "Readability counts". - correct answer "True or
False. A major drawback of Python is that Python code is more
difficult to read than code in most other programming
languages."
False. An algorithm can be described in English, pseudocode, a
programming language, hardware, etc., as long as the algorithm
precisely describes the steps of a computational procedure. -
correct answer True or False. An algorithm to solve this
,computation problem must be written using a programming
language.
True. An efficient algorithm is generally one whose runtime
increases no more than polynomially with respective to the input
size. In contrast, an algorithm with an exponential runtime is not
efficient. - correct answer True or False. An algorithm with a
polynomial runtime is considered efficient.
False. Many computational problems exist for which an efficient
algorithm is unknown. Such problems are often encountered in
real applications. - correct answer True or False. An efficient
algorithm exists for all computational problems.
True. Whether or not an efficient algorithm exists for NP-
complete problems is an open research question. However, the
current consensus is that such an algorithm is unlikely. -
correct answer True or False. An efficient algorithm to solve
an NP-complete may exist.
False. A linked list stores an ordered list of items. The links in
each node define the order in which items are stored. - correct
answer True or False. A linked list stores items in an
unspecified order.
True. A binary tree node can have no children, a single left or
right child, or both a left and right child. - correct answer
True or False. A node in binary tree can have zero, one, or two
children.
, True. The data stored in a list node can be a record with multiple
subitems. Ex: A linked list storing employee data might use a
record containing the employee's name, title, and salary. Also,
the list node itself can be implemented as a record, having
subitems for the data and the pointer to the next node. -
correct answer True or False. A list node's data can store a
record with multiple subitems.
True. Array elements are stored in sequential locations, so can
be easily accessed using an index. - correct answer True or
False. Items stored in an array can be accessed using a positional
index.
False. A programmer need not have knowledge of the underlying
implementation to use a list ADT. - correct answer True or
False. A programmer must know the underlying implementation
of the list ADT in order to use a list.
False. Different underlying data structures will require different
algorithms to perform same list ADT operation, which will have
different runtimes. Ex: For prepending an item to a list, a linked
list-based implementation is more efficient than an array-based
implementation. - correct answer True or False. A list ADT's
underlying data structure has no impact on the program's
execution.
False. No such conclusion can be drawn. The point of an ADT is
that the implementation is not known. - correct answer True
or False. If a list ADT has operations like Sort or PrintReverse,
the list is clearly implemented using an array.
